Since 1985, Hunter Douglas has offered superior energy-efficient window treatments that enable homeowners to be as comfortable as they are fashionable. Hunter Douglas products keep your home warmer in the winter and cooler in the summer. Hunter Douglas products help conserve energy at the window through Insulation, Solar Heat Control and Daylighting.

Hunter Douglas is the first manufacturer to earn a national energy performance rating and certification for interior window covering products through the AERC.  Using AERC ratings, consumers can select the perfect window treatments for their desired level of comfort.  Hunter Douglas offers a wide selection of AERC certified window treatments in the cellular and roller shade categories.  

It's a Big Deal

AERC ratings represent the amount of energy saved that would otherwise be lost through a window without a window treatment otherwise known as a window attachment.  Ratings are based on several factors: U-Factor, Solar Heat Gain Coefficient, how often shades are manually opened and closed on a daily basis, the baseline window, orientation, season and climate.

AERC's mission is to rate, label and certify window attachments in order to help homeowner, architects, and builders make informed decisions when buying energy-efficient products.
